I will know

[irinaofr]

Someone is saying something to me. I didn't know that before. My reply

1) I didn't know that. Now I know.
2) I'll know now
3) Now I'll know.
3) I'll know from now on.

Are all can be said?

Thank you.

Yes, although #2 would probably only work in certain limited contexts. The rest are all frequently used.

 

[teechar]

For that context, only #1 is possible.

Note, #2 and the first #3 are incorrect.
The second #3 may be possible in other contexts.

How about....let's say....

A: When you slam the door my shelf is shaking/my baby get scared.
B: Oh, I'm sorry, I didn't know! But I'll know that from now on. Won't happen again, don't worry.

Something like that. Will it work?

Thank you.

I don't think I'd use "I'll know ..." in that context at all. I might "I'll remember that from now on".

 

[irinaofr]

"You didn't know THAT?"
"No, I didn't. So what? I'll know now/ I'll know from now on.".

Still not?

Thank you.

I wonder whether there is a grammatical agreement between the future tense of the verb phrase "will know" and the adverb "now". In my opinion, "from now on" should be used in both 2) and 3).

I think in BrE if someone said to me "I'll know now" I would understand perfectly that they mean "I have new knowledge- it will serve me well next time I'm in this situation...." I wouldn't worry about the logical disagreement between the will and the now.

But I think we would more naturally say "I'll know in future." It's rather like making an apology to the other person, or making a promise...

"I'll know in the future"?

 

[tkacka15]

"I'll know in the future"?

Longman Dictionary of Contemporary English interprets "future" as an uncountable noun when used with the meaning "from now on":

"5 in future (used esp. in giving warnings) from now on: In future, make sure you get here on time."

 

[MikeNewYork]

In AmE, we would use the definite article. That has nothing to do with "uncountable".

 

[Peedeebee]

In BrE I think in the future would imply a time some distance ahead, somewhat disconnected from the current situation.

We would definitely say in future and that gives the idea of "from now on"/ "the next time I'm in a similar situation to this one ..."

We would use the phrase particularly for those times when we are doing it differently next time, learning from the experience.
